Yes, it's the weird request of the day.

I've built a prototype 93422 Ram tester and
while I'm 99.99% sure it's working I don't have
any actual bad chips to test in it.

Thanks,

I'd expect you could use a dead 5101 as well for your purposes? I may have a dead 5101 around in a batch of scrap parts I recently picked up...

That should work too.

I have a couple bad 93422s around here somewhere if you need to borrow them. Yes, as weird as it sounds, I'll need them returned.
 
I have a bad 2101A I just pulled last night. PM if you want it. Happy to help the cause.

(It's NOS, too! I think the soul is still in it.) ;)
 
I saw the Neoloch, but I have an old Ram tester and
didn't want to spend the $ just to do one other chip.

I threw this together and wrote the code all in 2 hours.

The tester writes 0-15 in each location and reads it back.

When the chip is done it blinks red for bad or green for good.

I simulated a bad location by writing a different value to various
locations that the read routine was not expecting.

Have you looked at neoloch? He developed a ram tester not to long ago. I picked one up and it's pretty nice.

here is his site
